Lacasse.

To all lwhom it may concern.'

Be it known that I, GEORGE S. JoHNs'roN, a citizen of the United States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Goggles, ofv which thelfollowing is a specification. l 7 This invention relates generally togoggles that may be applied to various uses; more particularly it isconcerned with a novel and improved form of goggle frame and guardassociated therewith Vwhich is of strong and simple construction, andpermits of the glasses or lenses being readi y withdrawn or replaced asrequired.

The features of this invention are susceptible of embodiment in a numberof different forms, a'few of which are suggested Accordingly, theobjects and purposes of this invention may best be vunderstood from thevspecification to follow wherein reference 1s made to the accompanyplanview of one form of the its associated parts removed;

Fig. 5 is a transverse section taken online Figs. 6 to l0 inclusive, aresimil-ar views resjiectively, of anot.herform of goggle.

The frames and guards of the devices that will now be described indetail are preferably constructed of some light, strong. and

suitable material, such, for instance, asr fiber,

or any serviceable composition that possesses the properties requisitefor this invention.

Figs -1 to 5 inclusive-A frame is employed consisting of two parts eachin the form of anv eye orbow 2l having a bridge piece 22 that is adaptedto cooperate with the other when .resting upon the nose. The two partsofthe frame are shown to be flexibly connected as by means of a strap2?.

Each eye ypresents an opening which is sub-V Spec'caton of LettersPatent.

stantially circular except for the provision of one or more projections24; and a leaf spring 25 all as best shown in Fig. 4. As a convenientmeans of securing the leaf spring in place, l have shown it to beattached to a U-shaped frame 2G that fastens to the bow, the springnormally acting to project into the circular area withinthe bow, buthaving` l thereof a recess 27 into which it may recede under pressure.The construction of the two eyes is identical, so that the samereference numerals have been applied to the corresponding parts of each.

rFhe mounting of the glasses or lenses in this goggle is so arranged andconstructed as to permit them to be readily attached or detachedrelative thereto and to hold them i immovably in place thereon. For thispurpose I employ a guard 28 of suitable shape and form to properlyexclude light and particles. and provided with a cylindrical por tionoesignated as 29 whose external diameter is slightly reduced at itsouter end 3P, an annular shoulder 31 being thereby provided, as shown.rhrough the wall of the guard in the thinned portion 30 immediatelyadjacent the shoulder 31, an Velongated opening 32 is provided extendingfor slightly less than 180 degrees so as to provide a means of entry orwithdrawal for a glass or lens 33 which is adapted to be seated within achannel 34 provided interiorly of the eye in a portion thereof notoccupied by the opening 32. The relation of the channel 34 and opening32 are best shown in Fig. Other shorter openings 35 are also arranged toregister with the projections 24, the thickness of the wall 23()adjacent such openings as at 36 being still further reduced for a reasonthat will presently appear. Each guard is equipped with a suitable cordor strap adapted to connect with the other when passed around the headso as to hold the goggle in place. this being suggested merely as aconvenient means for this purpose.

In assembling the glasses or lenses into the present goggle, the guardsare first removed so as to allow the glasses to be slipped into placethrough the openings 32. Each guard is then inserted within its eye 2land this is accomplished by a sliding movement accomare required toslide over the thinned porV tions 36 preparatory to lodging within theopenings These projections which connect the guard to the eye at twopoints are supplemented by the action of the spring 25 which projectsthrough the opening 32 into.

direct contact with the edge of the lens, the effect being' not only tohold the guard securely in place, but also to exert at all times apressure upon the lens tending to prevent any movement thereof withinthe guard. It is obvious Vthat a withdrawal of the lens yfrom the guardmay be effected' by a reversal of the operations described. j

Figs. 6 tri-10 inclusiva- A frame is employed consisting of two partseach in the form of an eye or bow 41 having a bridge piece 42 that isadapted to coperate with the other when resting upon the nose. The

VVtwo parts of the frame are shown to be flexibly connected as by meansof a strap 43. Each eye presents an opening which is substantiallycircular except for the provision ofV one or more projections 44, one ofwhich, designated as 45, is, according to this invention, carried upon aVresilient arm 46 integral with the frame, and adapted under pressure torecede into a slot or opening 47. Normally the arm 46 remains incircular alineinent with the eye 41 so as to main- Vtainits projectioninwardly Vof its inner periphery. The construction ofV the two eyes 1sidentical so that the same reference numerals have been applied to thecorrespending parts of each.

The mounting of the glasses or lenses in this goggle is so arranged andconstructed as to permit them to be readily attached or detachedrelative thereto, and to hold them immovably in place thereon. For thispurpose I employ a guard 4S of suitable shape and form to properlyexclude light and particles, and. provided with a cylindrical portiondesignated as 49 whose external diameter is slightly reduced at itsouter end 50, an annular shoulder 51 being thereby provided, as shown.Through the wall of the guard in the thinned portion 5() immediatelyadjacent the shoulder 51 an elongated Y opening 52 is provided extendingfor slightly less than 180 degrees, so as to providea means of entry orwithdrawal for a glass or lens 58 which is adapted to be seated within achannel 54 provided interiorly of the eye in a portion thereof notoccupied by the opening 52. The relation of the channel 54 and opening52 are best shown in Fig. 8. Other shorter openings 55 are also arrangedto register with the projections 44, the thickness of the wall 50vadjacent, such openings, as at 56, being still further reduced for areason that will presently appear. Each guard may be equipped with asuitable cord or strap adapted to connect with the other when passedaround the head so as to hold the goggle in place, this beingV suggestedmerely as al convenient means for this purpose.

In assembling the glasses or lenses into the present goggle, the guardsare first removed so as to allow the lenses to be slipped into placethrough the openings 52. Each guard is then inserted within its eye 41and this is accomplished by a sliding movement accompanied by a forcedrecession of the resilient arm V46 Yupon which is carried the projection45. During thisoperation theprojection 44 is required toslide over thethin portion 56 preparatory to lodging within one ofthe openings 55, sothat it may be snapped into place Within this opening.V Y Thisprojection 44 which connects the guard tothe eye at one point issupplemented by the other projection 45 which springs into anotheropening 52 where it directly contacts with the edge of theV lens, theeffect being not only to hold the guard securely in place, but also toexert at all times a pressure upon the lens tending to prevent anymovement thereof within the guard. It is obvious that a withdrawal ofthe lens from the guard may be effected by a reversal ofthe operationsdescribed.

rlhe several forms of goggle that have now been explained in detail areall simple in their constructiomand render facile a substitution ofglasses whenever this may be desired. In addition these constructionssecurely hold the glasses in place, and prevent leaks therearound.Obviously my invention is susceptible of embodiment in other forms thanthe ones herein suggested, and in respect of any changes ormodifications that may utilize the principle of lthis invention, asdescribed in the claims below, l desire that they should be includedwithin the scope of this patent.

I claim: i

1. A goggle comprising a frame'formed to provide two eyes each having aslotted bridge portion protruding from one side thereof, the frame offthe eye being severed at one portion adjacent the bridgeto provide anarm having capacity for receding into the slot, the arm carrying on itsmovable extremity an element normally projecting into the eye. a' secondprojection in another portion of the eye, al guard for each eye having acylindrical portion adapted for insertion therein, and a glass mountedwithin the guard, the guard walls having openings into which the fixedand movable projections may enter, the latter being required to recedetoward the slot as a condition preico Aed for insertion therein, andhaving means with which the element projecting from the arm may engageto lock the guard in place, substantially as described.
